The specific embodiment
Embodiment 1: on two ribs, sell
As shown in Figure 1, on the front end both sides of bracing frame 1, be respectively equipped with cushion rubber supporting plate 2, the rear end of bracing frame 1 is provided with the semicircle bayonet socket excessively of clamping roller mandrel; In the forward position, bottom surface of two cushion rubber supporting plates 2, be provided with outstanding front fin 3 downwards, fin 4 after being provided with after front fin 3, rear fin 4 is attached to the bottom surface of cushion rubber supporting plate 2, and parallels with front fin 3.The front table top of rear fin 4 corresponding middle bottom roller " T " character form structure in concrete use procedure.Spacing general control between rear fin 4 and front fin 3 is between 6-9mm.
Cushion rubber supporting plate 2 can be integrative-structure; But for avoiding occurring because front end wearing and tearing make the situation that whole upper pin is scrapped, cushion rubber supporting plate 2 also can be made into Split type structure, is divided into the front dop 22 of poppet body 21 and supporting plate, and before supporting plate, dop 22 cross-linkings are connected on the forward position of poppet body 21; Front fin 3 and rear fin 4 are distributed in the bottom surface of the front dop 22 of supporting plate.
The Bu Wei Plug Division, forward position of poppet body 21, the end face in this Plug Division is provided with two clamping projections 23, has 2-3 interspersed grooves (not shown) in the bottom surface of Plug Division; Before supporting plate, on dop 22, be provided with the inserting groove 24 from open rearward end, be provided with the interspersed rib 25 matching with interspersed groove on Plug Division in this inserting groove 24, before supporting plate, the end face of dop 22 has the block button hole 26 matching with two clamping projections 23.Before can making like this supporting plate, dop 22 coordinates comparatively tight with the grafting between poppet body 21.
The utility model also can arrange the spring with stretch function before poppet body 21 and supporting plate between dop 22.On the one hand, can dop 22 before poppet body 21 and supporting plate be linked together by pulling force; On the other hand, before also can making supporting plate by elastic stretch power, dop 22 moves forward, the reach of dop 22, must increase grid lasso 6(and see Fig. 2 before supporting plate) tension force, therefore, the spring with stretch function is set between dop 22 before poppet body 21 and supporting plate, when grid lasso 6 causes tension force not enough because service time is long, spring stretches, and the front dop 22 of supporting plate is moved forward, and then the tension force of increase grid lasso 6, make grid lasso 6 in tensioning state.Therefore, this embodiment can be avoided because grid lasso 6 tension force are compared with the little deviation phenomenon causing.And this embodiment has also changed the connected mode between poppet body 21 and the front dop 22 of supporting plate simultaneously.
Before supporting plate, the two ends of dop 22 are respectively arranged with limit convex along 27, spacing in order to grid lasso 6 is carried out, and prevent that grid lasso 6 from causing sideslip because left and right tension force is different.
End face side at cushion rubber supporting plate 2 is provided with sign convex edge 5, and sign convex edge 5 is relative up and down with the rear fin 4 of bottom surface, to play the effect of home position.By observation, identify the position of convex edge 5, can determine easily and accurately the position of the rear fin 4 on cushion rubber supporting plate 2 bottom surfaces, need not bend over the again position at from bottom checks fin 4 places of staff.
Embodiment 2: upper drafter
As shown in Figure 2, upper drafter is to be connected with roller mandrel 7 on the bracing frame 1 of selling on two ribs, and the two ends of roller mandrel 7 are connected with flexible rubber roll 8 by bearing.Roller mandrel 7 forms middle top roller with flexible rubber roll 8.Between the cushion rubber supporting plate 2 of selling, be socketed with grid lasso 6 on flexible rubber roll 8 and two rib.
The cross section of front fin 3 and rear fin 4 is the camber line of similar inverted U, and front fin 3 is combined to form the shape of falling W structure with rear fin 4.Rear fin 4 is by forming the first elastic surface jaw between grid lasso 6 and downside pin apron, front fin 3 is by forming the second elastic surface jaw between grid lasso 6 and downside pin apron.
Along with the transmission of grid lasso 6 and downside pin apron, make yarn priority warp fin 4 and front fin 3 later.The use of grid lasso 6, can make rear fin 4 and front fin 3 well drafting force be passed to the yarn between grid lasso and downside pin apron, because grid lasso is compared traditional apron, its effect of transmitting power is more obvious.If do not use grid lasso 6 in upper drafter, still adopt traditional apron, in front fin 3 place corresponding with rear fin 4, will can not form twice elastic surface jaw so, on two ribs, sell set front fin and rear fin and can not drafting force be passed to by apron to the yarn of below.Therefore, in the utility model, the setting of grid lasso is particularly important.
Grid lasso 6 carries out transmission by flexible rubber roll 8, use after grid lasso 6, if still use metallic roll roller, will certainly reduce the frictional force between the two, transmission effect is reduced, therefore, in order to guarantee to there is suitable frictional force between grid lasso 6 and roller, so that grid lasso 6 transmission along with the rotation of roller, the utility model is set to rubber roll roller by the roller (being middle top roller) of clamping in pin on two ribs, being used in conjunction with of itself and grid lasso 6, can make the gearing friction power of drafter meet instructions for use.
At the end face of cushion rubber supporting plate 2, be provided with the tensioning reed 9 of support grid lasso 6.The setting of tensioning reed 9, can prevent the deviation phenomenon that the tension force deficiency because of grid lasso 6 causes effectively.
The tensioning reed 9 arranging in upper drafter, its one end curves and hangs over the rear along upper of poppet body 21, also can be again with a U-shaped card on the rear edge of poppet body 21, to strengthen being connected between tensioning reed 9 and poppet body 21.Tensioning reed 9 supports, at the medial surface of grid lasso 6, make grid lasso 6 in tensioning state.After tensioning reed 9 damages, also can be changed easily.
